Just got word from our Motoleaker with the latest in X Fon news. As of now, only Sprint, Verizon and AT&T are major carriers confirmed to carry the device in the US. T-Mobile (perhaps because it already subsidized the similar-specced Nexus 4?) hasn’t yet finalized any deals with Motorola for the device.

The X phones will begin shipping to carriers in August and should be ready for back to school. The price is cheap enough for the carriers to subsidize the complete upfront cost, though it isn’t certain if they will or not. $300 is the current number being thrown around as the unsubsidized price (Again, like the Nexus 4).
